MainGrid

The MainGrid component is a standalone grid for displaying Dataverse records. Unlike SubGrid, it does not require a parent RecordContext — it loads records directly from a specified table or view.

Loading by Table Name

Set the TableName parameter to automatically load all public views for that table. The first default view is selected initially.

<MainGrid TableName="contact" />

Loading by View IDs

Use ViewIds and DefaultViewId to control exactly which views are available and which one is selected on load. You can also provide CustomViewDefinitions with inline FetchXML to define views directly in code.

<MainGrid ViewIds="_viewIds"
          DefaultViewId="@(new Guid("..."))">
</MainGrid>

@code {
    private List<Guid> _viewIds = new List<Guid>
    {
        new Guid("..."),
        new Guid("..."),
    };
}

Custom Views with FetchXML

Use CustomViewDefinitions to define views with custom FetchXML queries. This is useful for views that include filters based on the current user, linked entities, or other dynamic criteria.

Note

The Id for a custom GridViewDefinition must be a unique random GUID that does not correspond to an existing Dataverse view. If it matches an existing view ID, the Dataverse view will take precedence and the custom definition will be ignored.

private List<GridViewDefinition> _customViews = new List<GridViewDefinition>
{
    new GridViewDefinition
    {
        Id = new Guid("..."),
        TableName = "contact",
        DisplayName = "All Contacts",
        FetchXml = @"<fetch>
            <entity name='contact'>
                <attribute name='fullname' />
                <attribute name='emailaddress1' />
                <order attribute='fullname' />
            </entity>
        </fetch>",
        Columns = new List<ViewColumn>
        {
            new ViewColumn { ColumnName = "fullname", Width = 200 },
            new ViewColumn { ColumnName = "emailaddress1", Width = 250 },
        }
    }
};

DisplayName

Set DisplayName on a GridViewDefinition to provide a default label for the view in the dropdown selector without requiring a localization file entry. If a localization key exists at tables.{TableName}.views.{Id}.label, it takes precedence over DisplayName. This is useful for custom views where you want a readable name immediately without adding a localization entry.

Toolbar Buttons

The MainGrid supports the same toolbar buttons as SubGrid. For standalone grids, NavigateNewRecordGridButton and NavigateOpenRecordGridButton are commonly used to navigate to separate form pages. See the Grid Buttons documentation for a complete reference of all available buttons and their configuration options.

<MainGrid TableName="contact">
    <Buttons>
        <NavigateNewRecordGridButton Url="/contacts/new" />
        <NavigateOpenRecordGridButton Url="/contacts/edit?contactId={0}" />
    </Buttons>
</MainGrid>

Search Box Behavior

When the user types in the grid's search box, the configured view is automatically re-queried with additional filter conditions applied to every search-eligible column shown in the view. The conditions are joined with OR logic, so a record is included if any of its visible columns match the search term. The default match semantics differ depending on the column type.

Text and Lookup Columns

Text columns (string fields) and lookup columns (matched against the target record's primary name) use a starts with search by default. Typing joh matches values that begin with joh — for example John or Johnson. The match is delegated to FetchXML's like operator, which is case-insensitive in Dataverse.

Use * as a wildcard for more flexible matching. Typing *hn performs a contains-style match (e.g. John, Johnson); typing j*n matches values where any characters can appear between the j and the n (e.g. John, Joneson). The wildcard is converted to FetchXML's % wildcard at query time.

Choice Columns

Choice columns (option sets / picklists) and multi-select choice columns are matched against the localized display label of each option rather than the underlying integer value. Labels are compared case- and accent-insensitively in the current user's culture, so typing cafe will match an option labelled Café. When one or more option labels match, the query emits a FetchXML condition against the matching option values — an in condition for single-select choice columns, or a contain-values condition for multi-select choice columns. When no labels match, the column contributes no condition (keeping the OR filter compact).

Choice columns honor the same * wildcard as text columns: by default the match is starts with (typing act matches Active), and a leading * switches to contains (typing *act additionally matches Inactive). Matching rows have the matched substring highlighted in the grid, exactly like text-column matches.

Numeric and Money Columns

Numeric columns — int, big int, decimal, double, and money — support comparison operators in the search term. The search box parses an optional leading operator and applies the corresponding FetchXML condition operator:

  • = 100 or just 100  —  equal (the default when no operator is specified)
  • > 100  —  greater than
  • < 100  —  less than
  • >= 100  —  greater than or equal
  • <= 100  —  less than or equal

Note

Search conditions for every column type are added to the same OR filter group, so the same search term is evaluated against text columns, lookup columns, choice columns, and numeric columns simultaneously. Typing 100 in a grid that has both a name column and an amount column will match records whose name starts with 100 or whose amount equals 100. The search filter is layered on top of the view's existing filter, so view-level constraints (such as a statecode = 0 filter) are always preserved.

Disabling Search

Set AllowSearch="false" on the grid to hide the search box entirely. This is useful for grids that contain only a small fixed set of records, or where filtering is handled externally (for example via a custom toolbar).

<MainGrid TableName="contact" AllowSearch="false" />

Full Size Mode

Set FullSize="true" to make the grid expand to fill the full height of its parent container. This is useful when the grid is the main content of a page.

<PageLayout>
    <Body>
        <MainGrid TableName="contact" FullSize="true" />
    </Body>
</PageLayout>

Persisting Grid State

Use PersistedStateQueryParameter to persist the selected view, page number, page size, and sort to a single URL query parameter. The state is restored when the page is opened with that parameter present — useful for bookmarks and shared links. Pass IncludeSearchInPersistedState="true" to additionally persist the current search text (off by default since search terms can be sensitive).

<MainGrid TableName="contact"
          PersistedStateQueryParameter="gridState" />

Multi-Table Grids

A MainGrid can display views from different tables by including view IDs from multiple tables in the ViewIds collection. When the user switches views, the grid automatically loads the correct table's data. Use the OnClick callback on navigation buttons to dynamically set the URL based on the selected view's table name.

<MainGrid ViewIds="_viewIds"
          CustomViewDefinitions="_customViews"
          DefaultViewId="@(new Guid(AllContactsViewId))">
    <Buttons>
        <NavigateNewRecordGridButton OnClick="OnNewClick" />
        <NavigateOpenRecordGridButton OnClick="OnEditClick" />
    </Buttons>
</MainGrid>

@code {
    private async Task OnNewClick(NavigateGridButtonContext ctx)
    {
        ctx.Url = ctx.GridContext.SelectedView.TableName switch
        {
            "contact" => "/contacts/new",
            "account" => "/accounts/new",
            _ => throw new Exception("Unknown table"),
        };
    }

    private async Task OnEditClick(NavigateGridButtonContext ctx)
    {
        ctx.Url = ctx.GridContext.SelectedView.TableName switch
        {
            "contact" => "/contacts/edit?id={0}",
            "account" => "/accounts/edit?id={0}",
            _ => throw new Exception("Unknown table"),
        };
    }
}

MainGrid Class

Parameters

Name
Type
Default
Description
AllowChangingItemsPerPagebool
True
When true, the user can change the number of items displayed per page.
AllowDownloadForFileColumnsbool
True
When true (the default), the grid renders a per-row download icon at the trailing edge of file and image column cells. Clicking it streams the file to the user's browser. Set to false to suppress the icon — for example on read-only audit grids where file export isn't allowed.
AllowEditbool
False
Should the option be available for the user to turn on inline editing for the grid.
AllowNavigateOnPrimaryNameClickbool
True
When true (the default) and the grid has a registered 'edit' button (a GridButton with IsOpenRecordButton=true), the cell that renders the table's primary-name column becomes a hyperlink. Clicking it dispatches the same per-row invocation that a row double-click would — so a user can jump to the edit form (or the navigated edit URL, depending on the registered button) without first selecting the row. Set to false to suppress the hyperlink and render the primary-name cell as plain text. Has no effect when no edit button is registered.
AllowNavigateOnRowDoubleClickbool
True
When true (the default) and the grid has a registered 'edit' button (a GridButton with IsOpenRecordButton=true), double-clicking a row invokes that button's GridButton.OnClick for the row's record — opening the edit dialog or navigating to the edit URL, whichever the button does. Set to false to suppress the double-click handler. Has no effect when no edit button is registered.
AllowPreviewForFileColumnsbool
True
When true (the default), the grid renders a per-row 'eye' preview icon at the trailing edge of file and image column cells whose contents can be rendered inline (images, PDFs, plain text). Set to false to suppress the icon — for example on grids where the columns shouldn't double as a preview entry point.
AllowSearchbool
True
Should the user be allowed to search the grid.
BorderVisiblebool
True
Controls whether a visible border is rendered around the grid.
ButtonsRenderFragment?
Optional render fragment used to define the button toolbar displayed above the grid.
ColumnsRenderFragment?
Optional GridColumns fragment carrying consumer-declared GridColumn children. When supplied, the grid switches to replace mode: only the declared columns render (in declared order), the FetchXML projection is rewritten to match, and the underlying view's column list is ignored. null leaves the grid in its default behavior (auto-generate columns from the view's resolved column set).
CustomViewDefinitionsList<GridViewDefinition>?
Custom views to display in the dropdown.
DataSourceViewDataSource?
Optional shared Data.ViewDataSource. When set, the grid reads its rows + total count from the datasource instead of issuing its own RetrieveRecordsAsync(System.String) call — the same datasource can drive a sibling <DataverseChart> or a second grid so they all paginate / filter / search together off one round-trip. Standalone usage (no GridBase.DataSource) keeps the existing internal-state machine — the grid composes FetchXML and fetches via IPowerPortalsProService directly. What the datasource does NOT own: per-grid UI state (selected rows, pending row creates / updates / deletes, column widths). Those stay grid-local — two grids sharing one datasource can still have independent selection and per-grid pending edits. When ViewDataSource.Highlight is set (e.g. via a chart slice click in cross-filter 'highlight' mode), rows whose value in the highlighted column doesn't match are visually muted via a CSS class; the row data + selection are unaffected (the soft cross-filter is purely styling).
DefaultItemsPerPageint
50
Default number of records to load on a page.
DefaultViewIdGuid?
Id of the view that the grid should display upon initial load.
Editablebool
False
Is inline editing turned on for the grid.
FullSizebool
False
When true, the grid expands to fill all available vertical space instead of using a fixed minimum height.
HidePagingbool
False
Force the page size and paging components to be hidden. Only do this when the number of items is known and the page size is set to something greater than the item count.
IncludeSearchInPersistedStatebool
False
When true, the active search text is included in the persisted state URL parameter (under the q field). Defaults to false — search terms can be sensitive, accumulate in browser history, and leak into HTTP referrers, so the grid keeps them out of the URL unless the consumer explicitly opts in. Has no effect when GridBase.PersistedStateQueryParameter is not set.
IsDirtybool
False
Indicates whether the grid has unsaved create, update, or delete operations pending.
LoadedRecordsIEnumerable<TableRecord>
Records currently rendered in the grid (the most recent page of results). Intended for toolbar commands that need to act on 'everything shown' — e.g. a bulk download button. Does not span pages; bulk-across-pages operations should run their own unpaged fetch instead.
MaxHeightstring?
Max Height that the grid control should expand to.
MinHeightstring?
250px
Minimum height that the grid control should occupy.
ModeGridMode
RecordSelection
Sets the behavioural mode of the grid, such as default interaction or record-selection mode.
PageSizesIEnumerable<int>
Collection of available page sizes for the grid.
PagingModeGridPagingMode
Paged
Determines whether the grid uses traditional paging or infinite-scroll virtualisation.
PersistedRowsSnapshotPersistedGridRowsSnapshot?
Server-prerender → interactive handoff for the rendered page of rows. The framework auto-persists this property at the end of prerender and re-hydrates it before GridBase.OnInitializedAsync on the interactive side, so the data fetch can be skipped on first interactive render. Keyed by render-tree position by the framework; the PersistedGridRowsSnapshot.ViewId field is checked at consumption time so a rerender against a different view discards the stale rows. Public per the framework's requirement — [PersistentState] only sees public properties via reflection — but not intended to be set externally.
PersistedStateQueryParameterstring?
Name of the URL query-string parameter to persist the grid's interactive state to. When set, the grid reads this parameter on initial load and seeds the active view, page number, page size, and sort from it; subsequent user actions (view pick, page change, header sort, etc.) write the new state back via Components.NavigationManager's replace-state path. Persistence survives page refresh and bookmarks.
SelectedRecordsIEnumerable<TableRecord>
Records that are currently selected in the Grid.
SelectFromEntireRowbool
True
When true, clicking anywhere on a row selects it; when false, only the checkbox selects the row.
SelectModeDataGridSelectMode
Multiple
Controls whether the grid allows single or multiple row selection.
TableNamestring?
The logical name of the table whose public views should be loaded. Only applicable when no values are specified for GridBase.DefaultViewId or GridBase.ViewIds.
Titlestring?
Name to display when the view dropdown is not displayed.
TransformViewAsyncFunc<GridViewDefinition, Task<GridViewDefinition>>?
Optional callback that runs immediately after a view is loaded and before the grid uses it to build columns or queries. Return a modified Models.GridViewDefinition to transform what the grid ultimately renders — for example, to ensure a specific column is always present regardless of the view's own configuration. Async so callers can consult metadata caches, services, or other async resources while deciding what to include.
ViewIdsIEnumerable<Guid>?
